2025-04-21

Tesla is undergoing a significant vehicle architecture upgrade. They're replacing the legacy CAN bus with a next-generation network based on TDMA, enabling more efficient data transfer for high-resolution infotainment, OTA updates, and autonomous driving. Simultaneously, Tesla's 4680 battery, particularly its second-generation "Cybercell," is improving production efficiency, lowering costs, and enhancing vehicle performance. However, the launch of a cheaper Model Y has been pushed back to Q3 2025 or early 2026, suggesting Tesla is prioritizing its technological advancements and production optimization.
